Calculation Steps
Formula Used
Depth in feet: CY = SY × Depth ÷ 3
Depth in yards: CY = SY × Depth
Square yards measure area. Cubic yards measure volume. A depth value connects both measurements.

Frequently Asked Questions
Can square yards convert directly to cubic yards?
No. Square yards measure area. You must provide material depth.
What is the formula for inches?
Multiply square yards by depth inches. Then divide the result by 36.
How does waste affect the result?
Waste increases the required material. It covers cuts, spills, and uneven placement.
What is compaction allowance?
Compaction allowance adds loose material. The material becomes denser after installation.
Can I calculate square-yard coverage from cubic yards?
Yes. Select the reverse mode. Enter volume and depth.
Can I solve for missing depth?
Yes. Choose the missing-value mode. Select depth as the unknown.
What does order rounding do?
It rounds material upward. This matches common supplier ordering increments.
How are truckloads calculated?
The ordered volume is divided by truck capacity. Partial loads round upward.
How are bags calculated?
Enter cubic-yard yield per bag. The calculator rounds bag quantities upward.
Can I use several project sections?
Yes. Add sections with separate areas and depths. Their volumes are combined.
Should I always add ten percent waste?
No. Waste depends on material, site conditions, and installation accuracy.
